As the competition in the liner shipping industry is becoming fiercer, the shipping company is trying to find the way to keep the best competitive position by reducing the cost level as low as possible and offering the best quality of service to their customer. In order to achieve this goal, the selection of port and terminal that have the best quality of service and cost effective structure is essential for the shipping line, where they can only have a chance to save the money. In this context, the paper compares three European container terminals in order to understand the factors that have to be considered in the decision making process for the selection of terminal. And its advantages and disadvantages of each type of container terminal operation system were analyzed from the liner shipping company's point of view in terms of cost, time, flexibility, stability, hinterland connection, geographical position and terminal productivity. It is obvious that the cost factors are very important for liner shipping company to select their terminal. However, there might be even more important factors than the cost factors, such as quality of port and terminal service, mutual trust, and possibility of future development.

In this paper, we designed an inter-operation architecture of 10G G-PON(Gigabit passive optical network) network and NGN(Next generation network) architecture. And, we proposed mechanism of dynamic GEM(G-PON encapsulation mode) Port-ID allocation. This is able to solve a problem of 10G G-PON inter-operation. The mechanism of dynamic GEM Port-ID allocation has OMCI(ONT management control and interface) mapping table for IP address and port number. That architecture is able to support per flow QoS(Quality of service) as well as QoS of NGN requirement. So that can improve the resource efficiency of QoS than the existing G-PON architecture.

With the recent port environment, the integration of the separated berth is being actively progressed and the necessity of integration has been strengthening. Therefore, the application of existing gates have to review in order to reduce the truck turnaround time and to distribute the truck traffic volume in port container terminal. This paper analyzed the operation impact both the integrated gate and the separated gates. As the result of the analysis, this study suggests the separated gate system as an efficient design for gate operation considering integration of two individual berth.

The main subject to become a hub port is automation. The automated container terminal has already operated in advanced ports and it has been planned for the basic planning and operation design in domestic case. The key of automated container terminal is effective operation of both ATC(automated transfer crane) and AGV(automated guided vehicle) which is automated handling equipments. This is essential to productivity of automated container terminal. This study suggests the most optimal method of equipment operation in order to minimize loading time using each three types of effective ATC operation methods and AGV dispatching rules in automated container terminals. As the automated equipment operation causes unexpected deadlocks or interferences, it should be proceeded on event-based real time. Therefore we propose the most effective ATC operation methods and AGV dispatching rules in this paper. The various states occurred in real automated container terminals are simulated to evaluate these methods. This experiment will show the most robust automated equipment operation method on various parameters(the degree of yard re-marshaling, the number of containers and AGV)

Recently, container terminal managers make an experiment on the double cycle and dual cycle operation, which ship loading and unloading were carried out simultaneously, for increasing the productivity of quay side. If, however, we make an experiment on dual cycle operation in a real job site, the efficiency is poor up to terminal operation method as YTs(Yard Tractors)' allocation method, QCs(Quay Cranes)' working speed, and position of export containers. Especially, using the existing yard operation method, it is difficult to support to dual and double cycle operation. Therefore, this paper examine more efficient terminal operation method, when terminal uses dual cycle operation. We developed a simulation model using simulation analysis software, Arena.

Port operation is largely divided into gate operation, yard operation and berth operation. Operation strategy and optimal resource allocation for three parts are important in the productivity of the port operation.. Especially the resource allocation planning in berth operation needs optimization, because it is directly connected with the processing time in shipping. Berth planning is not independent on recourse allocation but interrelated with yard stacking area allocation. Therefore, we design the optimized module of berth planning and give priority to interrelationship with yard space allocation, while existing studies design independent resource allocation in berth planning. We suggest constraints by mathematical method, and they are related to yard stacking area allocation with existing constraints. Then we look for solutions, use tabu search to optimize them, and design optimized the berth planning module. In the performance test of optimized module design of berth planning, we find that the berth planning with yard stacking area allocation takes less processing time than without yard stacking area allocation.

Recently, 8,000TEU class containerships has started operating the shipping service and the mega-containership of over 10,000TEU is on planning. A unit cost in relation to shipping service is decreased by the bigger ship based on the economy of scale. Most of the previous studies have been performed and focused on the total operation cost from mega port to mega port. However, the purpose of this paper is to estimate economic efficiency of selected hub ports from point of view of total cost such as service cost(or operation cost), port charge and feeder cost, etc. First, the service-network of mega containerships is based on data of a domestic shipping company operated main line and economic analysis of individual scenarios on the cost and traffic when 10,000TEU mega containerships offer the services. The three scenarios presented in this paper set up the hub ports which are the port of Busan, Shanghai and Yokohama The results show that port of Busan is economically the most efficient one among others.

Being situated at the key point of northeast asia, the port of Inchon as an entrance to the captial city, Seoul is expected to play in marine transportation in Korean Pennisular on the verge of its reunification. In this thesis, inner-lock physical disstribution system of the port was analyzed, which treats more than 82% of total incoming and outgoing cargoes. The overall findings are as follows; 1. In thet viewpoint of physical distribution system of the port, it takes disadvantages of accessing to inner lock berth due to such natural restrictions as tides, passing the lock and so on. And insufficient port facilities as a whole, causes delay in quay-handling, transfer and storage, also facing with serious congestion in inland transport on the road. 2. It was revealed that the port facilities are insufficient yet in spite of its improved productivity by means of raising the effectiveness of port operation and of installing advanced cargo handling facilities. 3. In order to enhance the effectiveness of inner port physical distribution system , the improvement of lock facilities, expansionof port facilities and more effective terminal operating system are crucial. 4. To ensure the measures to solve the above problem, existent outer-lock ports such as Inchon Sourthern-port and Northern-port are necessary to be redeveloped more positively , otherwise a new port at outskirt of the city should be developed to ensure free connection to inland transportation.
